What are the 7 layers of OSI model or TCP/IP

The OSI stack was developed for a strict client-server architecture. One new "web centric" architecture is more like"
The old OSI client-server model does not apply to multi-tier 'web driven' architectures because presentation logic and personalization logic are at the top of the stack and application logic is moved to the middle tier.... this decouples presentation and personalization from application and publish-subscribe peer-to-peer services. OSI applies toward a specific class of client-server that predates n-tier.
Sorry, trick question
- Presentation Logic
- Personalization Logic
- Session and Session Security Logic
- Application Logic
- Information Sharing Logic
....lower level transport stacks here ....

after reading a paper about the OSI-model I'm not exactly sure how to look at this model.
Does data (a file) travel from the application level "down" each layer at the client

showmount
SHOWMOUNT(8) BSD System Manager's Manual SHOWMOUNT(8) NAME
showmount -- show remote NFS mounts on host SYNOPSIS
showmount [-Ae36] [-a | -d] [host] DESCRIPTION
showmount shows status information about the NFS server on host. By default it prints the names of all hosts that have NFS file systems mounted on the host. See NFS: Network File System Protocol Specification, RFC 1094, Appendix A, and NFS: Network File System Version 3 Protocol Specification, Appendix I, for a detailed description of the protocol. -A Search for NFS servers advertised via Bonjour. -a List all mount points in the form: host:dirpath -d List directory paths of mount points instead of hosts. -e Show the host's exports list. -3 Use mount protocol Version 3, compatible with NFS Version 3. -6 Use only IPv6 addresses to contact servers. SEE ALSO
mount(1), mountd(8), nfsd(8), mDNSResponder(8) BUGS
The mount daemon running on the server only has an idea of the actual mounts, since the NFS server is stateless. showmount will only display the information as accurately as the mount daemon reports it. HISTORY
The showmount utility first appeared in 4.4BSD. 4th Berkeley Distribution September 26, 2010 4th Berkeley Distribution
